From 62b72eafe49d2eecd3692691152ed86a0327fcb0 Mon Sep 17 00:00:00 2001 From: John Thomson Date: Thu, 19 May 2022 09:18:20 +1000 Subject: [PATCH] ath79: mikrotik: use OpenWrt loader for initram image Return to using the OpenWrt kernel loader to decompress and load kernel initram image. Continue to use the vmlinuz kernel for squashfs. Mikrotik's bootloader RouterBOOT on some ath79 devices is failing to boot the current initram, due to the size of the initram image. On the ath79 wAP-ac: a 5.7MiB initram image would fail to boot After this change: a 6.6MiB initram image successfully loads This partially reverts commit e91344776b9ba7c864be88d915c9c0df0eb790dd. An alternative of using RouterBOOT's capability of loading an initrd ELF section was investigated, but the OpenWrt kernel loader allows larger image.
